The International Space Station (ISS) is a modular space laboratory in low Earth orbit, jointly operated by NASA, Roscosmos, ESA, JAXA, and CSA. Launched beginning in 1998, it has been continuously inhabited since November 2000 and supports cutting-edge research in microgravity, Earth observation, and space technology, while fostering international cooperation.

What's happening outside the space station? A space shuttle has docked. Five days ago, the space shuttle Discovery was launched to the International Space Station, carrying six crew members and the large Leonardo Multi Purpose Logistics Module. Three days ago, as pictured above, the docked shuttle was prepared to be unloaded by the space stations Dextre robot and Canadarm2. The above expansive photo captures much more, however, including Japan's Kibo Experiment Module on the lower right, Earth across the top of the frame, and a seemingly starless backdrop of space in the distance. During the next week, the shuttle and ISS crews are scheduled to permanently attach Leonardo as well as fix and upgrade parts of the ISS. After 38 previous voyages, this is expected to be the last space mission for the Space Shuttle Discovery.
